Ko Kham is a small island near Ko Mak, on Trat Province, Thailand.
It can be reached with a sea kayak from Ko Mak or by walking during low tide. Ko Kham has nice places to snorkel, depending on the direction of wind. Especially the south beach has a calm sea, nice sand dyne, black lava rocks with shells and crabs (or crayfishes or shellfishes). Near rocks, you may see (or swim over) black sea flowers (? or does this belong to fauna) that have 15-30 cm radius and many thin black pipes about 30-50 cm long (don't know the name, help wanted). Locals say that the pipes contain small needles and poison: if one touches the pipes and gets the needles, the needle should be crushed with a rock. The poison is only irritating and not lethal. In Thai, the name probably is Hoi Ment.
